Stored well (not in a shipwreck off Bermuda), wine can certainly improve over time. The key is structure, which means good acidity and, for reds, firm tannins, plus enough fruit to balance those characteristics. Here, five affordable wines perfect for aging:
2014 Jim Barry The Lodge Hill Riesling ($18)
A dry Australian white, it will gain complexity and texture over five to seven years.
2012 Qupé Marsanne ($20)
This California white can be very long-lived—even the 1991 vintage is still lovely. Over time its flavors will evolve from crisp to honeyed and luscious.
